Campus parking division

Your strategy sounds reasonable. With regards to the "appropriate approach," this is always a bit of a guessing game because in my experience, it depends on the interpretation of your project's particular set of reviewers. In your situation, because the parking structure is part of a separate project beyond the scope or control of your project (at least that is how I interpret what you have said), you could almost claim "No new parking" - but, that could carry some risk - again, dependent on the specific reviewer's interpretation. I would suggest digging through the endless CIR's and LI's (on the USGBC website) to see if anyone else has had a situation like yours. That might help inform your specific approach. In the meantime, stick with your approach and I don't see why you couldn't claim 14 out of the 33 spaces being designated by the parking structure's design team - you will just need to plan this with them to distribute the spaces to be closest to the respective buildings utilizing the preferred parking. There is one thing of particular note to coordinate with that other design team: a recent LI ruling #10202 (see string below) dictates that ALL preferred parking must essentially be on the first level (with very few exceptions) citing "shortest combined driving and walking distance to building entrance". If you read the string below on this issue, you will find that most in here do not concur with the ruling and understand that assigning all preferred parking to the first level is counterproductive to the intent of these credits (SSc4.3 and SSc4.4). But, that is the LI ruling that is currently held to by the GBCI until further notice. Good luck!
